My D7000 and 300mm f4 AF-S arrived yesterday, within about 10 minutes of motorsport shooting this morning I realised something didn't quite seem right, even just reviewing on the LCD my shots were nowhere near as sharp as I would expect. I'm confident in getting a pretty solid hit rate at very slow shutter speeds, often down to 1/30 or so and on longer lenses than this previously, but it just wasn't happening.
Just to make sure it wasn't me I went well into my safe zone, 1/250 and faster, but I was still getting slightly out of focus shots. I then shot a few static objects such as signs at very fast shutter speeds (1/2000 ish), no matter what I just couldn't get them sharp. Everything seems slightly out of focus.
I've owned at least 6 or 7 cameras and 30+ lenses in the past few years and never had such an immediate and obvious issue, so I don't really know where I go from here...any tips?!
I have no other Nikon gear (cameras or lenses) to see if it's a wider issue.
